Japanese designer <b>< a href=" http://www.selfridges.com/cat/Junya-Watanabe/" style="text-decoration: none"><font color="black">Junya Watanabe</font></a></b> ensures you’re prepared for the season ahead with this shell <b>jacket</b>. Engineered with Gore-Tex technology – a microporous structure – its outer is durably waterproof and windproof as well as entirely breathable. Oversized in shape, you can comfortably layer up under this jacket depending on where you’re headed. If it’s just to the shops, emphasise the XL shape by teaming with dropped-crotch trousers. &nbsp;
